TO ALL WHOM IT MAY GONCERN:

vBe it known that we, THOMAS NEvISON, Jr., and JAMES NEVISON, of Morgan, in the county .of Ashtabula, und State `of Ohio, have invented certain new sind useful Improvementsin Carriage-Wheels; and we-do hereby declare that the following is a. full end` completedesciiption of-the same, reference being had to the accompanying drawings making part of this speciication, in whichi Figure is a side vienv of the whee v Figure 2 is a viewof` the edge.

Like letters of reference refer to .like parts in the dierent views. A, fig. 1,' represents the rim of the wheel, which is constructed and tired vin the usual way. B is the hub, which may be ofv wood or metal, as desired, and O the spokes. lhese spokes are made of thin, narrow steel springs, which, as will 'be seen, are continued straightin radial lines,'until they-approach near the'rim, and which urethenl curved abruptly, each in the same direction, forming a. semicircle, B', between the end of the straight` section of the lspoke and the rim. The spoke is continued along on the inside ofthe felloe, making thereby an inner facing or liningof. steel for the rim', giving to the same additional strength and durability.

As it'will be seen, each spoke is secured to the felloeby two bolts, d, and at the same time to each other,

the extreme end Of each spokebeing intruded under the bow of the preceding'one, thereby making the Aconnection of the spokes to the rim as irm and secure as the same would be if 'of one entire piece.

We do not com''ne ourselves .to the special curve given to the spoke, as shown-:1t B', bt-think that, as

shown at C', the best for obtaining thelargest eifective force of the spring.

i What I claimV asany' invention, and desire to secure by Letters Patent, is

`The herein-described wheel, when .the spokes of the sam-e are 'constructed' and secured to each other and' thefelloe or rim, in the manner substantially as set forth.
